« This book has been written for newcomers to assembly language programming. The reader is likely to have some experience in programming in BASIC, but will have come to realise its shortcomings, many of which can be overcome by use of assembly language.
Practical methods of designing and entering assembly code are emphasised, rather than the detailed study of each command, and the interaction between machine code and hardware is stressed.
The book will be of interest to all users of Z-80 based micros, including the ZX81, ZX Spectrum, TRS80, Video Genie etc. »
